Usage of "log_to_file" RunConfig param

How severe does this issue affect your experience of using Ray?

  • Low: It annoys or frustrates me for a moment.

Hello, I am fairly new to ray and I try to use Tuner with log_to_file option from the RunConfig.

As I can see in the documentation using this option, print statements for example should be captured and stored in trial directories in corresponding files that are created.

I have adapted the code of a basic example to include two print statements and run with the desired option into google colab. In this particular example I expect that stdout files are created inside the trial folders, along with result.json etc. However I can’t see any such files and the prints happen in the console. Am I missing something, or is there a configuration which overrides log_to_file somewhere?

Thanks
